SCRAPER DEVICE FOR CLEANING FLDOES AND Application filed September 27, 1921. 7 Serial No. 503,865.

1 o aZZ whom it may concern:

lie it known that 1,.Jorrn CECIL Dnvrnsozr, subject of the King}; of Great Britain, residing at Pahiatua, in the Dominion of New Zealand, have invented new and useful, improved Scraper Devices for Cleaning loors and @ther Surfaces, of which the following is a specification.

This invention relates to adevice that has been designed for use in cleaning surfaces such as the floors of milkingsheds, barns, stables, stores and the like, where accumulations of manure and dirt of various kinds likely to result. The appliance designed for this purpose is adapted to be pushed across the surface of the floor and to gather in front of it the debris accumulated thereon, and its construction is such that it may be provided with different forms of scraping edges so as to adapt it to any particular purpose. It is also so constructed that the scraping edges may be tilted up from the floor level when the appliance is to be drawn rearwards, thus allowing for it being used with a to and fro motion and for it running idly on the rear ward motion.

The device is formed by a pair of vertically disposed metal plates arranged to diverge from one another in broad V form and having a handle projecting rearwards from their point of connection. The lower edges of these plates form thescraping edges and for this purpose may be provided with renewable wearing strips of approved na ture. The device, especially in its heavier forms, may have combined therewith small. rollers or wheels mounted behind the plates and so disposed that when the device is tilted by levering the handle downward, the weight will rest on these rollers or wheels so that it may be drawn rearwards while its scraping edges are clear of the surface being cleaned.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a plan, and

Figure 2 a side elevation thereof.

According hereto two metal plates A.A of approved width and thickness and of equal length, are a ranged in vertical planes and to diverge outwardly and forwardly from one another to form the broad V shape shown. The spread of these plates may be of any desired width according to the purposes for which the appliance is to be used and the width of surface to be. operatedon at each operation thereof. The plates are secured together by any approvedmeans or lTlBllllOifl. In .the drawing they are shewn as being bolted together throuo'h flanges Bel} arranged face to face and rorinlng cont-inn ations. of the plates. These flangesare also shown as being shaped with bends 0'81? tending: longitudinallyin them and curving upwards (HICl I'GElI'WZLlClS so that when the flanges are placed together. a socket is.

formed by the two bends in which the handle D for operating the appliance is secured. The handle thus extends rearward and upwards at the proper incline to facilitate the working of the scraper. Any other approved manner of forming or attaching a handle socket at the rear of the jointing angle of the plates may, however, be adopted.

Each plate may also be formed with one or more corrugations E made longitudinally in its length in order to strengthen it against bending.

Along the lower edge of each plate, on its forward face, a wearing strip F is secured so as to project below the bottom of the plate and to act as the scraping or cleaning edge. This strip may consist of metal plate, or brushes, or leather or rubber wipers, as may be desired, and may be made removable so that when worn, a fresh strip may be put in its place.

An appliance is thus produced that may 'bev pushed across the floor or surface to be cleaned, the edges of the plates scraping such surface with a sliding action so as to remove any adhesive orloose dirt or other matter, which loosened matter then collects before the plates and is pushed along to any desired point. The weight of the appliance will ensure of the necessary frictional contact of the scraping edges with the surface being cleaned.

In order to facilitate the rearward travel of the appliance and to provide for it being worked to and fro over a surface in the same manner as that in which a lawnmower is worked, i. e., by moving idly on the rearward movement, a spindle G is arranged to extend transversely across the rear of the angle of junction of the plates and is carried in bearings G fixed on the rear faces of such plates. On thisspindle small wheels or rollers H are mounted so that they may rotate freely. These rollers are so adjusted in height that their peripheries just clear the placed flat on the surface and pushed forward, and then tilted on to its rollers and drawn backwards with its edges raised clear of such surface. I claim 1. A scraper cleaner for floors and other surfaces formed by a pair of vertically disposed metal plates connected end to end and arranged to extend forwardly and outwardly from one another, ahandle socket extending rearwardly from the angle of junction'of such plates and a handle inserted in such socket, substantially as specified;

2. In a scraper cleaner for floors and other surfaces constructed as described in claim 1, a renewablewearing strip fastened along the bottom edge of each plate and extending below such edge, substantially as specified.

3. A scraper cleaner for floors and other surfaces c'omprisedby a pair of vertically disposed metal plates connected end to end and diverging outwardly i and forwardly from one another, a handle socket extending rearwards from the angle of junction of the plates,ahandle inserted in such socket, and Wheels or rollers journalled on a spindle extending across the rear end ofsuch plates and beneath the handle socket, substantially as specified.

In testimony whereof, I afiix my signature.

JOHN CECIL DAVIDSON.
